Been fighting with the drive spindown on my laptop for years.
"Spin down! Now!!! Out out damn spot!"

Finally ran it in Win98 for a few days and discovered
it's just as bad (or worse). Some sneaky thing in BIOS spins
up my drive. I gave up on it.

Anyway --

Search for tips on running Linux on laptops,
they will tell you all about things like using hdparm to set the
spindown time and noflushd and things like that.

Here's a place to start

http://www.ibiblio.org/pub/Linux/docs/HOWTO/other-formats/html_single/Laptop-HOWTO.html#ss19.7

On Redhat, change the line in /etc/sysconfig/harddisks from
	EXTRA_PARAMS=
to
	EXTRA_PARAMS="-S 255"
for instance to set spindown to 21 minutes -- read the hdparm manpage
